Jim Apple created IMPALA-6020: --------------------------------- Summary: REFRESH statement cannot detect HDFS block movement Key: IMPALA-6020 URL: https://issues.apache.org/jira/browse/IMPALA-6020 Project: IMPALA Issue Type: Bug Components: Docs Affects Versions: Impala 2.9.0, Impala 2.8.0, Impala 2.10.0 Reporter: Jim Apple Assignee: John Russell
In the release notes, it says http://impala.apache.org/docs/build/html/topics/impala_new_features.html {quote}The REFRESH statement now updates information about HDFS block locations. Therefore, you can perform a fast and efficient REFRESH after doing an HDFS rebalancing operation instead of the more expensive INVALIDATE METADATA statement. {quote} However there is no change in HDFS or Impala side to support this. There may be some misunderstanding. After hdfs load balancing, user still needs to run INVALIDATE METADATA <table> to get latest block metadata. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
